i..\oin;n. a citizen of the United States, residing at liidn'eport, in the county' o t l* airfield and State of Connecticut, have invent-v ed certain new and useful improvements in Storage-Kittery Cells, of which the `l'ollowingis -a specification. i

.This invention relates` batteryhcells or tanks designed, especially tor use in connection with submarine tory duce a battery-cell or tank which shall be' stronger and more durable than those now in use, and one which, in the event of ingury to the inner acid holding jar, the ,acid or electrolyte will he prevented from comingy into leontaet with the outer metallic casing to thus insure against grounding of the hat tery elements, and also to prevent the de struction of the outer easing either by direct chemical combination with the acid or electrolyte, or by means of electrolysis'in the event or the outer casing becoming grounded through its supports or foundations.

The invention consists in constructing a battery-cell or tank of rubber or other acidfresistingr compound, and Iin arrangingr an envelop of lead over the lower end thereof which is burned vto a sleeve 'oi' lead carried by, and molded inthe upper portion of the said inner jar; in the sleeve of inca-conducting' arrangement ot' a material over thevuppcr end of thc inner pir, and in inelosingzthe `)ar thus constructed in a niet-allie easing.;` 'into which has been previously poured, in plastic state, a quantity of suital le non-absorbent and electrically ,noncomlucting waterproof substance of hardening plastic material, the casingr outer metallic icing of such a size relative to the 1nner jar, that when the latter is inserted intoy the ymetallic casing, the plastic l'non-comluctinteY waterproof ymaterial will be forced up` wai-illy into the recesses between volop and theintel-metallic casing, between the sleeve and thel outer and also metallic STORAG-BAT'ERY CELL.

, `The invention further consists in 'the em ,ploynient of a eoveror the cell `ortank, and in the 'peculiar and novel arranggen'ient foi-scalini;n the 'cover aii'- and gas-tight upon "the cell.

The invention further consists in certain ydetails of eonstructioi'is, combinations and arrangements o parts, and in vthe novel method' of assembling the eell or tank as' will be hereinafter fully described and then claimed.

These and `other `features egermane'thereto,

constitute -theinvention, as will be herein'- a'fter 'fully described and then claimed.

Molded in the `collar 2 is va band- 4 of lead. the lower edges with a pluralityH l u 10oA of which ext-end belowY the collar, and`-` to thus beingr made contiguous through the openings for the purpose of ancborngthe lead band within the collar. tlts sides,

As shown, the band 1lis of greater Width; on tiro of its opposite sides so as to tit under the flanges ll of the sleeve El, and the lead envelop 5, respectively. In practice, theband il will `be provided with grooves (Fig. l) so as to permit tbe asphaltuin,

hereinafter referred to, to flow from the lowerpseetion to the upper section of the tank when the saine is `beingr assembled, as will `be explained later on.

The ends of the sections 12 of the tank 10 are formed with ears 16 having` openings 1G', providing; lifting lugs for loweringr and ais-ing the tank or nell into :rnd out of po sition. The ettrenie upper" ende otlthe eollarflof 'the fp: 1 are-formed with a ron tinuous shoulder 17, jinovuhng a seat loathe `eover lS of the tank, and theu'alls of the 3er `l, and thefrertieal edges of the rover l-l.` aretormed with recesses l!) and 20, resinatirely, to provide seats for a iiexible gasket; 521, `preferably rubber, whereby the rover is seourely sealedktogthe jar or tank.

shown in Fig# 3), held in position, and also foi-red into `the recesses 1n and 20, bj a bandi preferably rectangular in Aeross senti on, and of euita b le non-oonduoting material or fonipound, and having: wedge-shape blocks Q3 'formed thereon, which are en- ;Iagedfby dogsi'lt carried at the outer ends of,liorimntally1 disposed members 25 jour,n naled at theininner ends` upon screws 2.6.` threaded into lugs 27 secured to the sides of the upper member 13 of the tank 10. The outer ends ot the members are `fitted in openings 28 formed in the upper ends of the dogs I24. When the tank assembledfland the plates are inserted therein, and the'eleetrolyte supplied thereto, the rover isthen placed in position, the members and the doersl24 earritul thereby havingIr previously been :swung-around upon their journals 26, as shown in dotted lines in Fig. 2, then when the rover baswbeen plaeed in position, the lun'izontal members are `swung around so that the dogsuill engage and ride upon A,the wedge-shapeblocks Qi to their farther` moet position, thus forcing the band 22 downwardly `to cause-the gasket 21 to be flattened ont and forced into the recesses 19 and 20,thus sealing the cover upon the tank. When the dogs Zlhave been thrown around to their extreme positimis,` tbe screws 26 are tightened `up to thus prevent the horizontal members .25 and the dogs 2l from slipping, thurs holding the eoverin position.

rlhe asseinblinnigF ot' the tank is as fol lou'ew-l'lhe inner jar l with the insulated lead sleeve or band. Jr is first molded and the envelop in than drawn over the jar l; the appel-ledger: of the envelop being then` burned or otlwrwise (,:onnerted to the lower edges nl the band "l at the `point 40, indicated in lilies. l and El.

the 'lead liningp The lead lining-Will then f bavethe potential ofthe elements` contained within the Jar, but this potential is pre4 rented fromypenetrating to the outer metal@ lieeasingbyemeans of the Vinsulation provided by `thornsidating' compoundA ,30 intel`- posed: between the lead lining and the mel tallic tank,- `and between'the sleeve and the Ala edges of the inner jar,

, aisance v said tank. ln no case, however, will it be possible for the outer metallic casing to obtain a potential from the contents ot the .inner jar except through the possibility of the upper surface of the cover and the upper edges oi' the jar becoming moist with. 'electrolyte through leakage around the joints ot the vcover or through failure to perfectly seal the openings through the battery terminals, (not shown)` leading through the cover. .ln the event of any possible leakage whereby the electrolyte ina-y reach the upper metallic casingthrough-creepage over the upper surface of the cover and the upper high resistance connection between the outer metallic casing and the 'elements ofthe cell. The potential thus caused would be very slight, and owing to the .very high resistance interposed, such potential may negligible. When the plates are inserted within the tank and the jardL is supplied with the electrolyte, the top 18 is then secured in 'position as r' l have not thought it necessary to show the plates in the cell, nor the connections through the cover 18, as this will be well understood by any one skilled in the art to which the invention rela-tes.

Vvhile l have shown and described the inner jar l as having aband #i cast therein, and an envelop 5 of lead surrounding the lowery end of the jar,l desire it understood that the envelop inclose the entire -body of the pir l and the hand 4, thus dispensed with, and l, there fore, donot wish to confine my invention to the arrangement of a 'band l being cast or molded into the upper end of` the jar, nor to the specific arrangement of molding the jar with the' collar 2. However, the construction shown-and described is preferable over any previous constructions heretofore employed.

ll/'hile l have band 29, as constructed of non-conducting lmalerial. l desire it turther understood that l do not limit n'iyself to the employment of'a band of' such material as it is evident the band maybe made of any metal not affected by electrolyte, as the band may be constructed ot .a core of any desirable metal and covered with preferably antimony lead. In either fase, itwill be understood that a sullicient number of dogs 24 will be em.- ploycdfor forcing the band 22\tightly against the gasket 21 without deforming the said band, consequently to hold the over tightly against its seat with uniform pressure.

(lf course, when the band 22 of metal is employed, the dogs 2l will necessarily be constructed of some n on-comlucting material. However, in instances where the said band 22 is conthus establishing a` be considered previously described.'
